GAS-RANGE.

Specification of Letters Patent. Pat t June 13, 191

Application filed February 17, 1914. Serial No. 819,273.

To all whom it may concern.-

Be it known that I, GUY B. CHILD, a citi- Zen of the'United States,residing at Chicago, in the county of Cook andState of Illinois, haveinvented certain new and useful Improvements in Gas-Ranges, of which thefollowing is a specification, reference being had therein to theaccompanying drawmg.

y gas ranges.

The object of my invention .is to provide a gas range having anair-inlet and exit so arranged and connected to the gas controllingvalve that the opening and closing of the gas valve opens and closes theair-inlet and exit, whereby the heat of the oven is retained and at thesame time providing means whereby the burners cannot be lighted withoutthe inlet and exit openings being opened and thus avoiding any liabilityof explosion in the oven.

Another object of my invention is to provide means whereby the passageof the products of combustion are utilized for heating the oven and whenthe burner is extinguished the heat accumulated thereby is utilized infurther cooking the articles in the oven and maintaining the oven at ahigh temperature.

A further object of my invention is to provide a simple, cheap andeffective oven of this character having certain details of structurehereinafter more fully set forth.

In the accompanying drawing: Figure 1 is a perspective view of myimproved oven, showing the valve and damper operating means and showingthe burner and lower damper in dotted lines. tive view of the bottom ofthe oven, showing the relative position of the burner and the lowerdamper. Fig. 3 is a vertical transverse sectional view of Fig. 1 showinga fine oppositethe-upper damper. Fig. I is a horizontal transversesectional view taken on the line 44, of Fig. 3, and showing the burnerand the lower damper in dotted line.

In the ordinary gas range, it is necessary to have an air-inlet at thelower end of the oven to supply the proper amount of fresh air to theburner to cause combustion, and also to provide an exit opening at theupper end to allow the heated air and products of combustion to passfrom the oven. In such ovens these'openings have been of such ainvention relates to improvements m cause perfect combustion.

Fig. 2 is a perspecp stove on the inside of the door-'3, is a tubecharacter that when the burners have been extinguished the oven is stillsupplied with the air and the heated air also passes from the oven. Thisallows the oven to become cool in a very short time and also allows thesame amount of air to be supplied and discharged from the oven when theburners are running full, or only partially burning. This, as Wlll bereadily understood, supplies the oven with more air than is necessary tocause the proper combustion and thus it takes more gas to heat the ovenat the desired temperature than is the case with the device which I willnow proceed to describe.

The oven 1 is of the usual rectangular form and supported by feet 2 andhaving at its forward side the door 3, which is located some distanceabove the bottom 4: of the oven and below the top 5. .All of this is ofthe usual construction and needs no further description. The bottom 4:of the oven is provided with a hinged damper 6, hinged by a horizontalpivot 7, the outerend of said pivot extending outwardly and having anoffset portion 8 extending beyond the side 9 of the oven. The extremeouter end of the offset portion 8 of the pivot 7 is bifurcated, asindicated at 10, and to which the operating means is adapted to beconnected, as hereinafter more fully described. a

Within the oven, above the opening 6, which is closed by the damper 6,is a burner 1%),1 which is of any desired form but prefera y whichsurrounds the opening 6 and whereby through the opening 6 the properamount of air is supplied to the burner to Extending inwardly from thefront of the 12 which is slightly inclined and extends adjacenttheburner 11 and has an enlarged portion 13, which is adapted to straddlethe space between the tubes 14 and 15 of the burner and communicateswith the gas-discharge opening 16 therein. By this structure it will beseen that in order'to light the burner it is only necessary to open theoven door and apply a match to the outer end of the tube. The gas in thetube 12 is ignited and travels down and ignites the two tubes 14 and 15at one end and the flame then travels across and ignites the entireburner, all of which will be readily understood.

Above the burner 11, is a heavy-cast-metal plate 17 which has its rearedge spaced a distance from the rear wall 18 of the oven and leaving aspace 19 for the products of combustion and heated air to pass upwardly=r into the oven proper 20. This plate 17 is closed by a damper 22, thepivot 23 of which extends outwardly beyond the side 9 of the oven and isprovided with a laterally turned portion 2e. having its outer endbifurcated at 25. Extending transverse the oven, be-

, low the opening 21, is a heavy cast-metal plate 26 which divides theoven and forms a passage 27 across the upper end thereof. The forwardend of the plate 26 does not extend to the front of the oven, thusleaving a space 28 through which the products of combustion and heatedair pass into the passage 27 and out through the opening 21 and aredischarged to the atmosphere. The products of combustion engaging boththe lower and upper faces of the cast-metal plate 26, it will be seenthat the same will become heated and when the oven is shut up this platethrows off its heat and keeps the oven hot for a great length of time.Surrounding the discharge opening 21 is a vertically disposed flue 29,which, if desired, can be connected to the chimney.

The burner 11 is supplied with gas through the pipe 30, which issupported by the brackets 81, and said pipe carries the valve 32 throughwhich'the air passes to the funnel-shaped member 33 and by means ofwhich the burner is supplied with the proper amount of air and gas. Thevalve 32 is provided with a valve-stem 34 carrying a bifurcated arm 35between which is pivotally connected a bar 36. This bar 36 extendsupwardly and has its upper end screwthreaded into a socket 38, pivotallyconnected at 39 to thearm 39 of the member 40. This member 10, as shownin Fig. 1 of the drawing, is pivotally mounted upon the pivot 41,carried by the plate 42, said plate being riveted or bolted to the side9 of the oven. The member 40 is provided with an arm 43 to which ispivotally connected the socket as and to which is screwed a rod 45, thelower end of which is pivotally connected between the bifurcated end 10of the pivot of the lower damper 6.

The member 41-0 is provided with an up- 7 wardly inclined arm to towhich is pivotally connected a socket and into which is screwed a-ro'd458, and the outer end of the said rod is pivoted within the bifurcatedend 25 of the pivot 23 of the chamber 22. The rods 36, 4:5 and 48, asheretofore described, have screw-threaded connections with the sockets38, 44 and 47, whereby said rods may be adjusted so that the dampers andalso the valve will be thrown the proper distance to open and close thesame.

The plate 10 is provided with an outwardly extending operating arm a9,which is adapted to engage the segment 50, carried by the side 9 of theoven and whereby the lever is held in its adjusted position. By thissegment it will be seen that the lever 19 and the plate -10 are held inany position so that the burner is closed, opened or partially openedand when in such a position the lower damper 6 and the upper damper 22are in a corresponding position. The lever 49, as shown in Fig. 1 of thedrawing, is in a position with the gas full open and the upper and lowerdampers also open. lVhen the lever is swung down to the closed position,as indicated at the lower end of the segment 50, the gas will beentirely out off and the dampers 6 and 22. will be closed, whereby theoven is tightly closed and will retain its heat.

Vhen the gas is entirely cut off and the dampers 6 and 22 are closed, asheretofore described, it will be readily understood that there being noair supplied or discharged from the oven, the oven will be kept at ahigher temperature for a greater length of time than is the case withthe ovens now in use, in which air is supplied and discharged after thegas is cut ofi. The cast-metal plates 17 and 26 throw off considerableheat and greatly aid in maintaining the high temperature of the oven fora greater length of time.

Having thus described what I claim and ters Patent is:

1. The combination with an oven, of a burner therein, a gas controllingvalve for the burner outside of and located at one side of the oven, theoven having an outlet opening at its top and an inlet opening at itsbottom, pivoted dampers for the said openings having their pivotsextending to the same side of the oven as the gas valve, an operatingmember composed of a plate pivoted to the same side of the oven as thegas valve, said plate having four integral arms extending radiallytherefrom in substantially the same vertical plane, two of said armsextending substantially horizontally therefrom and connectedrespectively my invention, desire to secure by Let- 'with the gas valve,and with the pivot of the lower damper, the other two arms extendingupwardly, one of the upwardly extending arms being short and operativelyconnected with the pivot of the upper damper and the other upwardlyextending arm elongated to form an operating handle, whereby the saidarms and the operative connections are located at the same side of theoven and in substantially the same vertical plane.

2. The combination With an oven, of a burner therein, a gas controllingvalve for the burner outside of and located at one side of the oven, theoven having an outlet opening at its top and an inlet opening at itsbottom, pivoted dampers for the said openings having their pivotsextended to the same side of the oven as the gas valve, and an operatingmember composed of a plate pivoted to the same side of the oven as thegas valve and extending in a vertical plane alongside of the outer sideof the oven, the said plate having a plurality of integral Copies ofthll patent may be obtained for five cents each, by addressing thelaterally extending arms operatively connected respectively With thepivots of the two dampers and With the gas valve, and an operatinghandle for the plate extending substantially parallel the outer saidside of the oven, whereby the said arms and operative connections arelocated at the same side of the oven and in substantially the samevertical plane.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
